ABSTRAKT

In this study, surface alloying of carbon steel with tantalum is carried out using nitrogen compression plasma flow (CPF). The action of relatively short (~100 µs) and high-energy (up to 20 J/cm2) pulses of CPF results in melting of both the near-surface layers of a steel substrate and pre-deposited Ta film (~700-nm thick). Rapid liquid-phase mixing in the molten layer exposed to the plasma flow results in the formation of new phases during fast re-solidification. The results show that the thickness of the alloyed layer depends on the absorbed energy value, and the number of pulses is between 8 and 12 µm. An increase in the number of pulses provides a more uniform tantalum distribution in the modified layer. The mechanical and tribological properties of the samples after plasma treatment are significantly improved. The maximum degree of hardening was raised by more than a factor of 2.5 after five 9-J/cm2 pulses of CPF.
